l vide: a form' of locking device for securing i bodyingthis invention.

' is seated in the seat 13 ant clencher and other pneumatic tires u onthe rim of a wheel in a manner which Wil erniit of readily 'removing thetire without t e use of tools and at the same time prevent thepossibility'of accidental releaseof the tire. Thisj 'object risaccomplished by the device shown inl the accompanying drawings, in

l l L Figure 1 is atransverse section of a Wheelrim and tire lockingdevice constructed 'acordingto-niy invention, the same beingshownjasappliec'l to a double-tube tire of the Fig. 2 is a top plan,partly broken away, showing a portion of the rim and locking-ring at thepart where the lockiiig-ring'is .withdrawn and inserted into its seat!Figs 3 and 4 are transverse sections of rims,`f"showing modifiedr formsof rims em- Fig. 5 is a view. of the locking-ring removed from the-rim.

lnftvhdform shown 1n Fig. 1 -the rim 6 has a cylindrical periphery 7-andis curled up at' 8 alongL one edd'e of its periphery to tit the usualcleiicherange 9 of the tire 10'. The other.' clencher-lange 9 'of thetire .is engaged by a'retainingvring 11, which tits upon the peripheryol thefrim and is removable thereiromfto permit of access to theinnertube of the tire. Theedge of the rim which is adjacent totheretaining-ring 11 is curled upon itse'lfat 12'to fornithe seat '13,which extendsaround the'rim andhas a contracted slot' 14, openingthrough. theperipliery. The interior `Mof- Ithe seat l13 is ofconsiderably greater width than the slot 14.' The retaining-rin 1]. isheld against being forced side- Wise o of the rim through pressure ofthe tire vby means of a split loclin l-ring 15,'Which il extendsoutwardly beyond the periphery, so as to form an annular'stop bearingagainst the side of the retaining-ring 11. `The locking-ring 15 ispreferably split at an angle, as shown at 16 in Fig. 2, and the rim hasa channel 17, which extends spirally outward from the seat 13 to theadjacent edge of the rim. :The

channel 17 is disposed at an angle to the seat 13, so that the resilientlocking-ring 15 ma be slid endwise into its seat. The lockingring 15tits loosely within the seat 13, so that v when the tire is deflatedsaid locking-ring may be readily turned circumferentially around theperiphery of the rim for inserting and withdrawing it from its groove.,The`

ring 15 has apin-hole 21 in its outer face to permit the insertionof anail or pin for assistinor in shifting said locking-ring. The inner edge18 of the locking-ring 15 is enlarged to fit the interior of the seat 13and prevent i the ring from springing radially outward of the seat. lThis enlargement is preierabl in the form of a bulb or beading extendinga ong the entire lenvth of the riiw 1G. The same purpose would'lbeaccomplished by enlarging the edge of the locking-ring only at certainlintervals of its length. It will therefore 'be understoodthat the wordbeading as here' ,inafter used in the vclaims isintended to includeeither ofthe'hereinbefore-mentionedl. i

structures or their equivalent.

In the form shown in Fie 3 the edge 8 of.

the rim is bent outward to Form a retainingfian e, and bothclencher-langes of the tirev are eld by removable retaining-rin s 11.The locking-ring 15 is moved toaslig t extent by formin the retainingbeadin or bulb on one side on y and making the ot er side' straight.

In the form shown in Fig. 4. the lo'ckin.

'ring 15 is made exactly the same on eac side, so as to beinterchangeable end for end in its seat. The rim in..thjs vcase isalso..

formed of two parts" joined and bolted together along the seat 13. Thisconstruction I" is Erneferred'in cases Where the rim is tobe sb jectedto extremely' hard service.

such cases the outer part 19 of the riI'n may y bememoved to permit theAremoval of the locking-ring 15 when through accident the rim has becomebuckled so as' to prevent the rotation of the rin 15 and its withdrawalthrough the charme '17 in the usual manner.'

The operation Aofvthe device shown is nis follows: The tire is firstplaced upon the rim,

cent to each other Within the groove 13.,

The l cking-,ring should preferably be tln'nedl far enough to bring the'joint 16 at a point slightly' beyond the channel 17'` As soon as thetire is inflated its pressure against A the retaini ng-ringv 11 forcesthe same out- VWai-diy against ,the locking-ring 15 and prevents vtheossibility shifting witin its seat.

When it is desired to remove the tire or to gain access to the innertube, the air is permitted to escape from the tire, and as soon as'thetire has become deiiated the ressure .0f the retaining-ring 11 upon theocking- 15v will be released. Since the bead 18 itslcosely in the seat13, the locking-rin may now be readily rotated in its seat, an its end20- may be sprung slightly toward one side, so as tol permit it to passout of the channel17.

What Lclaim as my invention, and desire to secure by Letters Patent,is'- 1'. A vehclerwheel comprising a rim hav edge thereof, and alocking-ring, separate 'from the tire, Imounted in said seat and eX-tendi-ng outwardly beyond the. periphery of the rim for` retaining atire thereon, said seat and the adjacent portion of said ring beingformed toslide circumferentially into interlocking engagement with eachother for preventing said rin from springing out of said seat-in aradial irection. 4

2'. A vehicle-wheel comprising a rim having an annular seat extendingaround one edge thereof, and a split locking-iing, sepaf rat'e from thetire, mounted in said seat and extending outwardly beyond the rim forretaining atire thereon, said seat and the adjacent' portion of saidring-y being fornied to slides! circuinerentially into interlockingengageinent with each other for preventing said rin from springing outof said seat in a radial direction-'ay v vehicle-wheel comprising a rimhav-l ing aseat extending around its periphery, saidseat comprising aslot having an enlarged. interior, a locking-ring extending around andbeyond the periphery of said rim and having a beaded edge fitting Withinsaidr seat' and adapted to prevent the ring from springing' out of theseat, said rim having therein a channel leading spirally oute waedlyfrom said seat toward one edge of the m31, said rin being split at anoblique angle and adapt to be passed endwise through said channel intosaid seat;

4. A vehicle7whee1 comprising a rim havof said locking-ring ing anannular seat extending around one' ing therein a seat, an endlesstire-holding'v ring mounted on Said rim, and a locking device seated insaid seat and engaging said ring to prevent the same from slnftinvlaterany Off of the rim, Said making device'iaving interlockingengagement with the seat independent of said ring and adapted to preventsaid locking device from being sprung transversely out of the seat, andsaid seat being .adapted to permit said locking device to be withdrawntherefrom when moved longitudinally of the seat.
